where E is the effective Young’s modulus of porous material with porosity p, E0 is Young’s modulus of solid material, pc is the porosity at which the effective Young’s modulus becomes zero and f is the parameter dependent on the grain morphology and pore geometry of porous material [1]. As was noted by Wagh et al. [2], fittings of the experimental data to Equation 1 often give pc= 1 [1, 3] and do not explain the data accurately. In recent experimental works, either pc≡ 1 is preferably used [4–6… Expand
On Correlating Elastic Properties of the Porous Structure to Pore Attributes
The correlation between the stiffness and porosity of the porous material is studied for many decades. In most cases the goal was to propose an equation correlating the fractional change in elasticExpand

A simple linear equation is proposed for prediction of Young's modulus, E, from %RR, at least in the porosity range between 0.1 and 0.3 (representative of commercial pharmaceutical tablets), but use of %RR instead to E is applicable only under many limitations. Expand
Influence of the Total Porosity on the Properties of Sintered Materials—A Review
Porosity is a characteristic present in most sintered materials, full densification only being achieved in special cases. For some sintered materials, porosity is indeed a desired characteristic,Expand
